WINDOW RAISER.

Application filed April 3, 1924. Serial No. 703,856.

To all 'whom t may concern:

Be it known thatwe, ANDREW E. SCHMITT and Pirrnn F. BUCK, citizens of the United Stat-es, and residents of Sandusky, in the county of Erie and State of Ohio, have invented a new and useful lVindow Raiser, which invention is fully set forth in the following specification.

Our invention has for its object to provide an efficient automobile window-raising device and one wherein the window may be positively locked in any one of a plurality of positions to which it may be raised.

The invention may be contained in window raisers of diiferent. forms. To illustrate a practical application of the invention we have selected a structure containing the invention as an example of such structures, and shall describe it hereinafter. The window raiser selected is shown in the accompanying drawings.

Figure 1 illustrates a side view of a door, the inside sheet covering material being shown partly broken away to illustrate a part of the window-raising device. Fig. 2 illustrates a side view of the window raiser and Fig. 3 illustrates an edge view of the device. Fig. 4` is a sectional view, taken on the line 4 4 indicated in Fig. 2, of a wheel used in raising the window.

rThe window-raising device may be used for raising windows located in the door or any other part of the automobile. In Fig. 1, 1 is a door in which the window 2 is located, the door being provided with suitable guiding channels for maintaining the window in position. rilhe window raiser is secured to the framework of the door, such as to the cross pieces 3 and 4, by means of the screws 5.

rEhe device has a sheet metal strip 6 to which the parts are connected and thus the device may be installed in an automobile by merely securing the supporting strip 6 to the frame of the automobile. A vertical rod 7 is secured to the strip 6 near the upper and lower ends thereof by means of the posts 8 that secure the rod parallel to and in spaced relation with respect to the strip 6. A lazytongs may be pivotally connected to a suitable fixed pivot pin located at any point in the lazy-tongs. In the form of construction shown, the tongs are provided with two sets of links and is pivoted to a fixed pin located in line with the center pivot pins or points of the lazy-tongs. The lazy-tongs 10 may be provided with any number of sets of links to produce any desired upward movement relative to the movement of any one set of the links. The post 8 located at the lower end of the rod 7, has a cylindrical portion or a pin 9 and the lower links of a lazy-tongs 10 are pivoted on the pin S). A bushing 11 may be located on the pin 9 to hold the lower links of the tongs 10 in position, and yet permit pivotal movement of the links. An-

other of the center pivot pins is provided with a head 12 having a bore for receiving the rod 7 whereby the movement of the lazyt-ongs is guided along the rod 7. The pin 13 having the head 12 is connected to a means for raising and lowering the lazytongs. In the form shown, it is connected to the cable 14 by means of the cable connector 15 having an opening for receiving the pin 18 and which may be forced on to the pin 13 to securely connect the cable to the pin.

The cable 14 extends to a wheel 16 having a groove 17 located in its edge. One end of the cable 14 is" secured to the wheel 16 and a portion of the cable lies within the groove 17. Vhen, therefore, the wheel 16 is rotated the cable 14 is drawn upwards which raises the lazy-tongs. rIhe weight of the lazytongs and the parts connected thereto will lowerthe lazy-tongs when the wheel is ro-.

tated in the opposite direction. An arm 18 may be connected to the wheel for the purpose of rotating` the wheel. They wheel may be pivotally supported between the strip 6 and a bracket 19 having suitable bearings' for receiving the pin or shaft 20 to which the arm 18 is connected.

rPhe upper center pin of the lazy-tongs is also provided with a head 21 having a bore through which the rod 7 extends to guide the upper portion of the lazy-tongs and to maintain the lazy-tongs in parallel relation with respect to the rod 7. A bracket 22 is connected to the head 21 having an upwardly extending flange .3. The window 2 is provided with the usual supporting channel bar 24 extending across the lower edge of the window 2.

The inside of the channel bar is provided with a lip 25 that is turned downward and which may be placed on the flange 23 of the bracket 22. Thus the bracket 22 sustains the weight of the window 2 and connection is made between the window 2 and the window-raising device.

ln order to positively sustain the window in any one of aplurality of positions tov which it may be raised bythe rotation of the wheel 16, means is provided for loclr.

ing the window. In the form of construction shown the window-raising device is provided with a fiat bar 26 that may bexformedv from sheet metal and which is pivoted by means of the pivot pin `27 near the upper end of the rod 7. The bar 26 is provided with notches 2S for engaging the inner end of the pin 13. The bar 26vmay be pivotally connected to the strip 6 so as to cause the bar 26 to normally swing towardsthe pin. 13 andso as to place the notches 28 in position .of engagementwvith the pin .13 eX- cept when the bar 26,is positively yswung away from the `'pin 13. Thus the upper end of the bar may b e provided with a laterally extending arm 28 in which theA pin 27'is located and also the bar 26. may beprovided with aiwidened lower end to load the lower end of the bar on the sideopposite topthat from which the arm 28 extends. To guide the bar 26 and maintain it in its poy sition notwithstanding its lateral lswinging movements, the lower end oi' the bar vmay be provided with a slot 29 in which a fixed pin 80 secured in the strip; 6 may be Ilocated.v The pin 30 may be provided with a suitable,

head to retain the bar in position on the pin.v Also if desiredVandin order to pre vent rattling of the bar as the automobile proceeds over theroad, the bar may be elastically drawn towards `the pin 18 by means of the spring 31 which is connected at one. end to the bar 26 and at the other end to,`

thev strip 6.

'In order to positively move the bar 26 to release its engagement with the pin 18, the periphery .of the wheel '16 is provided with a plurality of lugs 82 which engage the edge of the bar 26 to swing it away from the pin 13 when the window is to be lowered. Thus the notches 28V are suitably' formed in the bar withi'espect to the position of the lugs 82 on the wheel 16 at'such ponts. that the pin lgwill reach the succeedi-ng notches 28-in advance of the-times when the lugs 32 engage the bar 26 during the lowering'ofvthe window, the opposite being true when the window is raised. By thislarrangement the window may be raised to any one of a plurality of points and the Y pin lwillbe engaged by the bar 26. When the window is to be lowered, a lug 32 will liirst push the bar `26 to one side and there Vbeing some lost motion in the parts.v When thev bar 26 is pushed to one .side theload of the window operatingvthrough the lazy.- tongs is placed upon the cable .14.

We claim: A1. In awindow-raising andlowering device, lazy-tongs connected yto a fixed pivot pin forming vone of the central pivot'pins .of the y,lazy-tongs, another Ycentral pivot vpin of the lazyetongs for connecting. the windowlto the,lazytongs, a cable connected to another ofthe centralpivot pins,imeans for operating the cable to raise and lower the window and ardog having; a lplurality of .pins of the lazy-tongs, a` rotatable member connected to another of, the central lpivot pins of the lazy-tongs, a dog4 orsecuring another of the central pins of thelazy-tongs in the Aposition to which-it may be movedby the said member, and `said member having lugs for engaging the dog and toy release the dog from the central; pin withwhich itis in .Y engagement.

In testimonyAvhereof, rwefhave hereunto signed our names `to this. specification.
